Title: Warning device for detecting state of surface
Inventor: TAKAKUBO YOICHI
IPC: G01B11/30
Filed: 1984-07-30
Abstract: PURPOSE:To call an operator's attention for cleaning and replacement of a disk, by comparing the detected signal of the state of the surface of an optical information recording medium with a reference signal, operating a control device when it is judged that the information is hard to reproduce, and issuing warning of sound, light or others. CONSTITUTION:Light emitted from a light source 12 is made to be parallel light by a lens 13. The parallel light is projected on the surface of a disk 15 at a certain angle. The reflected light is further reflected by a mirror 14. The light 17, which is repeatedly reflected by the disk 15 and the mirror 14, is inputted to a light sensor 18. In order to find the state of the entire surface of the disk 15, the light source 12 and the lens 13 are moved in the directions of arrows. The energy of the light 17 is conspicuously decreased when contamination, dust and the like are present on the surface of the disk 15. The output signal of the light sensor 18 is inputted to a comparator 21 and compared with a reference voltage 20. The difference is detected and a warning generating signal 22 is outputted.

Title: Electrophotographing method
Inventor: NISHIKAWA MASAHARU
IPC: G03G13/22
Filed: 1980-11-12
Abstract: PURPOSE: To selectively obtain good positive and negative copy images, by using a photoreceptor formed by laminating 2 photoconductive layers each sensitive to the light in a first or second wavelength region different from each other, respectively.  
     CONSTITUTION: A photoreceptor 25 has photoconductive layers 23, 24; the layer 23 sensitive to the light in the first wavelength region (the visible light) and the layer 24 sensitive to the second wavelength region (the ultraviolet rays). This receptor 25 is subjected to visible light image illumination with simultaneous charging, then, uniform exposure to the ultraviolet rays, and a positive electrostatic latent  image is thus formed. On the other hand, the receptor 25 is likewise subjected to light image illumination with simultaneous charging, destaticization of the whole surface potential to almost zero, and uniform exposure to the visible light, thus forming a negative static latent image. The obtained positive or negative image is developed and transferred by allowing a negatively charged toner 28 to act on said image to form a positive or negative copy image, thus permitting a good positive or negative copy image to be selectively obtained.

After that, if necessary, the polycrystalline silicon film 13 is doped with impurities like P. After an oxide film on the surface of the polycrystalline silicon film 13 is eliminated, a V film 141/a Ni film 142/an Au film 15 are formed in this order by using a sputtering method or the like. After the Au film/the Ni film/the V film are patterned, devision into chips is performed. Since the oxide film on the surface of the polycrystalline silicon film 13 is eliminated before a metal multilayered film 16 of V/Ni/Au is formed, adherence between the metal multilayered film 16 and the base film is improved.

Title: Noise reduction device
Inventor: ISHIMOTO SHUNEI
IPC: G11B20/02
Filed: 1988-06-27
Abstract: PURPOSE:To generate a signal almost equivalent to a recorded voice signal and to reduce a head switching noise by reducing the noise by connecting the start point and the end point of the head switching noise by a linear interpolation circuit. CONSTITUTION:The carrier frequency of a frequency modulated voice signal receiving band limitation by a band-pass filter 5 is compared with the carrier frequency at the time of frequency-modulating the voice signal at a carrier frequency comparator 8, and a pulse is generated first by a hold pulse generation circuit 9 when the deviation of two carrier frequencies is generated. The start point of the head switching noise is judged by the pulse, and the end point of the head switching noise is judged by the pulse outputted when the deviation of the two carrier frequencies is restored to an original state. Meanwhile, the voice signal demodulated at a frequency demodulation circuit 7 is delayed at a demodulation signal delay circuit 10 so as to fit the timing of interpolation. Here, the voice signals at the time of the start point and the end point of the head switching noise are connected by the linear interpolation circuit 11. In such a way, it is possible to reduce the noise remarkably.
